With little warning the salty warmth of my Master's cum explodes in my mouth. The clinking of the chain leash against my thin metal collar stops as my attention shifts to swallowing every last drop of the thick liquid. It always catches me off guard how much of it there is, and I can feel my lungs burning for air as more of it is pumped into my mouth.
Finishing, my lips break the seal with a wet 'pop' and my eyes drift upwards to my Master, my heart speeding up as I anxiously wait for his approval. But he's not even looking at me, a book in his hand blocking my view of his face. My heart sinks at this realization and I slump a little on my knees, my eyes drifting to the floor.
A gentle tug of the leash brings my attention back upwards, and I shiver a little as I see him peering over the book at me.
"Open." He speaks clearly and firmly, his voice leaving little room for thought. I quickly straighten my posture and open my mouth wide for him. His eyes glare callously at me, examining my mouth to make sure not a drop of his cum remained. He leaves me suspended in anticipation for what feels like hours, his gaze roaming around my naked body as if searching for something out of place. It's moments like these where I most feel like his slave, so small and helpless before him.
The creaking of his armchair breaks the tense silence as he rises, I scramble backwards on my knees to give him space. He pulls his softening cock back into his pants and zips up the fly. In a single motion he gives the leash a firm tug, signaling me to follow, and turns towards the basement door.
"Bedtime slave." His tone is much more neutral, causing a sense of relief to wash over me knowing I succeeded in pleasing him with my mouth. Crawling after him quickly I'm able to avoid any painful tugs on my collar. He opens the heavy wooden door and flicks on the lights before stepping inside. Crawling down the stairs is still tricky, but he lets me take my time, waiting for me at each step.
Reaching the bottom of the stairs we're finally in the basement. It's a bare concrete room with a single light dangling from the ceiling. A simple metal wall locker is fixed adjacent to the door, and a small cage rests in the center of the room. I follow my Master to the door of the cage, and kneel patiently as he bends over to unlock it. The subtle ache of a nearly full bladder pulses through me, and I suddenly feel anxious again. As the cage door is opened in front of me I consider the long night alone, and I know I have to say something now.
"M-master?" I say timidly my body automatically tensing as he pauses.
He replies after a moment, "What is it slave?"
"I-I have to pee, M-master." My eyes drop to the floor as I feel shame wash over me. He sighs in evident annoyance and I brace myself for his anger.
"Wait until morning, it's time for bed." The ache pulses through me again and I raise my head to protest, but the cold tired glare he gives me sends my eyes right back to the floor.
"Yes, Master." I reply solemnly before slinking into the cage. It's not big enough to stand up or lay down, so I lay uncomfortably curled up on my side with the metal bars pressing into my back. Master closes the cage and locks it, then reaches a hand into the cage and unclips the chain leash from my collar. He turns without saying a word and begins climbing up the stairs. "Goodnight Master!" I call out after him as the heavy door creaks shut. The lock clicks and the lights go out, leaving me alone in the dark.

I awake shivering in a cold sweat, it's still dark and I have no way of knowing what time it is. But judging by how painfully my bladder is aching I must have been asleep for a few hours. I shift uncomfortably in the cage, trying to find a position that puts less pressure on my bladder, but there's no relief. My heart races knowing my only hope is to wait for morning when my Master will let me out, but that could be hours away. The darkness and silence of the basement does little to reassure me, and there's nothing else to focus on besides my need. Giving up on sleeping I shift to a kneel, but the ache quickly causes me to double over in discomfort, my hands gripping the bars of the cage tightly.
And then it happens, the dam bursts. I let out a wail as warmth cascades down my thighs, pooling on the cage floor. My hands squeeze the bars tighter but I can't stop it, the puddle spreads to my knees as I'm emptied. The ache is gone but in its place is an equally agonizing sense of shame and dread.
****
The sound of the lock clicking and the blinding flick of the light switch alerts me of my Master's arrival. I would normally have felt relief, but this time all I feel is fear. Each footstep on the stairs is like a ratchet locking me one step closer to the edge. I'm still on my knees, and I sink my head low feeling a blush already spreading on my cheeks. His morning slippers enter the top of my vision, and I can feel his hot gaze on my back.
"Bad Girl!" His voice hits me like a slap across the face, "I told you to wait until morning!"
